Dense glass-ceramic articles obtained by additive manufacturing of glass frits are provided. A method of forming a glass frit for additive manufacturing includes: providing a mixture having at least one silicon (Si) compound, at least one calcium (Ca) compound, and at least one zirconium (Zr) compound; at least 1400° C. The mixture was melted at a temperature of 1000 Å; the mixture was cooled to room temperature to obtain a glass frit comprising: at least 50 wt % SiO 2 , at least 30 wt % CaO and at least 10 wt % ZrO 2 . |
